WRENCH.

Application nl ed September 14, i922. Serial No..588,438.

To all l1071.011?, 'it may cof/wem: Be it known that I, JOHN lPineau,Jr., a citizen of the United States, residing at Milwaukee, in thecounty of Milwaukee and State of Wisconsin, have invented certain newand useful Improvements in Wrenches, of which the following is aspecification.

My.k invention relates Yto improvements in so called Socket wrenches, anobject being to, provide a compact and reliable construction which maybe used in places which are ordinarily very inaccessible and which canalso-be operated by means of a lever handle in the usual way or by meansof gearing.

A further object of my invention is to provide a wrench which willenable inaccessible nuts to be manipulated without difiiculty, which canbe easily and quickly adjusted and which is not-liable to break or getout of repair. A further object oi my invention is to provide a wrenchthat is strong, durable, simple and inexpensive in construction and thatis well adapted to the use for which it -is designed.

Other objects and advantagesY of the invention will become apparentduring the course of the followin description.

In the` drawing, lw erein like numerals are employed to designate likeparts throughout the same,

Figure 1 is a longitudinal section taken through my improved wrench inits assembled condition,

Figure 2 is a section taken on line 2-2 of Figure 1 looking in thedirection of the arrow,

Figure 3 is a section .taken on line 3-3 of Figure 1 looking in thedirection of the arrow, and

Figure 4e is a detailed construction oi a semi-'circular collar used inaccordance with my invention.

In the drawings wherein for the purpose of illustration is shown thepreferred embodiment of my invention, the numeral 5 designates anangular housing, which is provided at one end with the internal',

threads 6. A tubular handle casing 7 is adapted tobe connected to oneend of the an thread 6, said tubular handle casin 7 being adapted toreceive a tubular hand e 8, one end of which is provided with anoperating lever 9 and the otherl end ofwhich is provided with a beveledgear 10, which is keyed gular housing 5 by means of the screw to thereduced portion 11 of the handle 8. The handle 8 is provided with anannular groove 12, 'said groove 12 being positioned within the tubularhandle casing 7. A semicircular bearing, which is carried by the tubularhandle 7 means of a set screw 14 is adapted to ri e in the annulargroove 12 in the handle 8. It will thus be seen, that the semi-circularbearing 13, will guard the handle 8 against a latter movement within thetabular casing 7.

As is clearly shown in Fig. 1 oi the drawing, the beveled gear 15 isadapted to mesh with the beveled gear 10. The beveled gear 15 is carriedby a socket member '16 which is mounted in the other end of the angularhousing 5. The socket member 16 is provided with the annular groove 17which is adapted to receive a semi-circular bearing 18 similar to thesemi-circular bearing 13, and is carried by the angular housing 5 bymeans of a set screw 18. It will thus be seen that the semi-circularbearing 18 will prevent the pinion 15 Jfrom sli ping out of mesh withthe gear 10. It is ound convenient to make the top of the socket member16 flush with the end of the angular housing 5. The socket member 16 isprovided with a recess 20 which is adapted to receive a socket wrenchmember 21.

In use, this wrench can be operated by I means of the lever handle 8within the housing- 7, in the usual way or if it is desired it maybeused by means of the gearing. It is of course to be understood, thatthe wrench socket member 21 is interchangeable, or, that is that varioussized wrench members may be inserted in the recess 20 within the member16. The wrench socket member` 21 is adapted to en age a nut 0r the like.The lever 9 may e rotated in either direction, according to whether ornot it is desired to screw or unscrew the nut. Therotation of the lever9 will rotate the handle 8 Within the housing 7, said handle 8v beingguarded against lateral movement by means of the. semi-curcular bearings13 driving in the groove 5. As

the beveled gear 10 is keyed to the reduced end 11 of the handle 8, thebeveled gear 15 will be caused to rotate in the same direction, thereby.rotating the wrench socket member 21. It will thus be seen, that I havedevised a very simple form of wrench, that may easily be used on theordinary inaccessible nut, and its value. is enhanced by reason oftheinterchangeable wrench member 21. The number of working parts has beenreduced to a minimum, so that the possibility of my improved wrench ofbecominghtemporarily out of order, is done away wit It is to beunderstood that the form of my invention herewith shown and described isto be taken as the preferred embodiment of the same, and Various changesin the shape, size and arrangement of lparts may be resorted to, withoutdeparting from the preferred embodiment of my invention or the scope ofthe subjoined claim.

Having thus described my invention, I claim p A wrench of the classdescribed comprising an angular housing, a socket receiving membermounted in one end of said angular housing, a. bevel gear 'carried onthe opposite end of' said socket wrench receiving a bevel gear at theinner end of the operating member meshing with the first mentioned bevelgear, a handle casing for receiving said operating member, both of saidmembers provided with annular ooves, a semi-circular bearing receivable1n each groove, and screws receivable in the housing and casing forholding the semi-circular bearings in place.

In testimony whereof I aiix my signature in presence of two witnesses.
